Astoria, Oreg.

Application December 7, 1931. Serial No. 579,387 2 claims. (o1. s1 '164) This invention vappertains to new and useful improvements in wrenches.

The invention is primarily comprised of a body element having a removable body engaging head associated with the outer end of the body -element. A threaded member is disposed longitudinally of the body element. A guideway is disposed at one side of the body element into which an adjustable jaw support is slidably disposed. A toothedremovablehead is disposed Within the adjustable -jaw support anda threaded stem is disposed about the lthreaded member and 'is adapted for being moved along the threaded member as the handle is rotated and for also moving the adjustable jaw support longitudinally of the body element. A handle member is disposed upon one end of the body element, to'

facilitate handling the wrench and for imparting rotation to the threaded stern.

and large objects to be held or turned.

A still further object of our invention consists in so constructing the device that removable heads are adapted thereto that may be easily interchanged, when desired, for any purpose.

A still further object of our invention consists in so constructing the wrench assembly that the adjustable head may be maintained in a suitable lubricated condition to facilitate the easy adjustment of the adjustable head. Y

A still further object of our invention consists in so constructing the wrench that the same will have longevity;

With these and incidental objects in View, the invention consists in certain novel features of construction and combination of parts, the essential elements of which are set forthV in the appended claims, and a preferred form of embodiment of which is hereinafter shown with refer.-

ence to the drawing which accompanies and forms a part of this specification.

Like reference characters refer to like parts throughout the several views.v

Our device is primarily comprised of a body element 1. A guide guard 2 is formed integral witli'the body element and is disposed at the head end of the body element and outwardly extends therefrom. A handle 3 having a roughened surv face 4, is rotatably disposed upon the handle 'Z0 end of the body element. The body element is hollow for the major portion of its length, as illustrated at 5, and a threaded stem 6 is rotatably disposedwithin the hollow portion of the body element. The threaded stem has a journal bearing 7 disposed upon its rearwardly extending end and is adapted for being journaled within Va journal formed within 4the end wall 8 of the -body element. The threaded stem terminates in a squared end 9 and thevsquared end 9 is 80" adapted to engage within a like orifice, or opening 10 that is disposed within the rear wall 11 of the handle 4. The terminal end of the threaded stem is threaded as illustrated at 12 to adapt a closure nut 13 for being secured thereto. The 85' stem -is enlarged as illustrated at 14, to form a bearing between the threaded stem and the inner wall of the body element 1. A jaw 15 is removably secured to the jaw end of the body element, as through the use of a set screw 16. An adjustable jaw support 17 is slidable relative to the-body element and is adapted for being maintained in alignment and in registry with the body element, by the guide 2. The guide 2 is closed as at 18 at its rear end to adapt the guide for 95 maintaining a lubricant carrier 19 therein and the top and bottom Wall, of the adjustable jaw support are made to precisely fit the inner Walls of the guide and the inner top vwall of the body element. A jaw 20 is removably secured to the head 21 of the adjustable jaw, the same being secured thereto by a set screw 22.

A recess 23 is formed within the head and the same is adapted to receive and lock the lug 24 105 of the removable -jaw 20 therein. A recess 25 is also formed within the jaw end of the body element and a projection 26 is disposedupon the outer end of the removable jaw 15 which is adapted to fit within the recess.

A slot 27 is disposed longitudinally of the top of the body element. A recess 28 is formed Within the adjustable body 17 and a nut 29 is threadably disposed upon the threaded stem 6 and the outer end of the nut engages Within the recess 28 and moves the adjustable jaw support longitudinally of the body element as the threaded stem is rotated through the rotation of the handle 3. j

While the form of mechanism herein shown and described is admirably adapted to fulfill the objects primarily stated, it is to be understood that it is not intended to confine the invention to the one form of embodiment herein shown and described, as it is susceptible of embodiment in various forms, all coming within the scope of `the claims which follow.

What We claim is:

1. In a device of the class described, the combination of a hollow tubular body element, a guide guard outwardly extending from the head end ofthe body element and formed integral therewith, a handle rotatably disposed at the opposite end of the body element, a threaded stem rotatably disposed within and longitudinally of the body element, the threaded stem having a journal bearing upon its outer end that is journaled within a bearingformed by the body element, a driving contact disposed between `the threaded stem and the handle, an adjustable jaw support slidable relative to the guide guard and to the body, a recess disposed Within the underside of the adjustable jaw support, and a nut coacting with said threaded stem and adapted for being moved longitudinally of the body element and extending through a slot in the side wall of the body element, and coacting with the recess disposed within the adjustable jaw support for projecting or retracting the same with respect to one end of the body upon rotation of said threaded stem.

2. In a device of the class described, the cornbination of a hollow tubular body element a guide guard formed integral with one end of the body element and extending outwardly therefrom, a tubular handle embracing the opposite end of thebody element and rotatably mounted thereon, a stationary jaw removably secured to the outermost end of the body element and guide guard, a jaw support slidably mounted Within the guide guard and provided on its outermost end with a removable jaw, a threaded shaft rotatably mounted within the body element by bearings at both of its ends and having one of itsv ends engaged With the rotatable tubular handle, a traveler nut threadedly engaged with the threaded shaft and adapted to travel therealong, said nut being formed with an upwardly extending and integrally formed projection adapted to be embraced by a notch formed in the slidable jaw support.
